Answer:
b. forward mutation, suppressor mutation
Explanation:
When the nucleotide sequence of an organism is altered, it is called as mutation. It can be caused by DNA damage or replication errors. In forward mutation, the wild type allele is converted to a mutant version such that the gene product is non functional or its not produced at all. Suppressor mutation is the second mutation which reverses the phenotypic effects of the previous mutation. This process is called as synthetic rescue.
Since here gene X was converted into a mutant form by the mutation, it had undergone forward mutation. When gene Y was mutated, the function of gene X was restored which ultimately also restored the phenotype hence it is an example of suppressor mutation.
Answer:
The red blood cells will burst or rupture when it is diluted and it will be one transparent and visible. ... Because water is an hypotonic solution, water from outside of the cell to the inside making the cells to continue to swell up and rupture ,a phenomenon known as haemylosis.
Answer:
The correct answer is - The Dobzhansky-Muller Model.
Explanation:
The Dobzhansky- muller model is a model that explains about how the natural selection influences speciation or reproductive isolation in a specific process when hybridization takes place between 2 species of an organism.
The offspring that produce through this process is an incompatibility with other species of origin. In the given question, spotted platyfish that arise due to the X linked gene exhibits the Dobzhansky-muller model.
Thus, the correct answer is - The Dobzhansky-Muller Model.
Answer;
The above statement is true
One type of personal health monitor measures the amount of time you spend in REM sleep.
Explanation;
-Fitness tracker or monitors have the ability to monitor or track the shut-eye during sleep.
-These trackers all continuously monitor the movements of the eye during sleep and also assess sleep-wake cycles to ascertain whether an individual is in deep or light sleep.
-Some of the trackers incorporates heart rate data to get a better sense of how deep one is into their sleep.
